I replaced the fuel pump and let it idle for a while, and it sounded like it fixed it. But 5 minutes later the car died while idling, and stumbled upon startup. Once it starts, I "clear it up" by giving it some gas and it seems fine. But it will die again, and when I took it around the block, it jerked again, but then clears up.

Any other troubleshooting steps I can take? I know my o2 sensors have not been changed ever! (173K miles), and the front o2 sensor is slightly damaged. I'm going to replace it to see if that works as it probably needs to be replaced anyway, but can anyone think of anything else?
